Live-Debug Runtime Diagnostics

Product scope: This skill builds and manages Live-Debug ServiceTask diagnostics on Alibaba Cloud CMS (aliyun cms2 apm service-task) and queries capture results via SLS. It does not onboard APM/agents and is not a general CloudMonitor (CMS) management skill.

Prerequisite Check

1. Check aliyun exists - which aliyun (macOS/Linux) or where aliyun (Windows).

• Not found -> ask the user to install the aliyun CLI first: https://help.aliyun.com/document_detail/121541.html. Stop and wait.

2. Check CLI version - run aliyun version. Minimum required: 3.3.15 (see compatibility in frontmatter).

WARNING: Compare version segments as integers (semver): 3.3.4 < 3.3.15 because 4 < 15. Shell verification: printf '%s\n' "3.3.15" "$(aliyun version)" | sort -V | head -1 If the output equals the current version, the requirement is NOT met.
